The compute nodes of the CPU cluster of system Lise are organised via the following slurm Slurm partitions.

Which partition to choose?
If you do not request a partition, your job will be placed in the default partition, which is standard96.
The default partitions are partition is suitable for most calculations. The :test partitions are, as the name suggests, intended for shorter and smaller test runs. These have a higher priority and a few dedicated nodes, but are limited in time and number of nodesprovide only limited resources. Shared nodes are suitable for pre- and postprocessingpost-processing. A job running on a shared node is only accounted for its core fraction (cores of job / all cores per node). All non-shared nodes are exclusive to one job , which implies that full NPL are paid.
Details about the CPU/GPU types can be found below.
The network topology is described here.
